After a plane crash, Tammy attempts to explore the Hidden Grotto within Mumbo Jungle. Unfortunately, she sets off a trap at the entrance, which sends a whole bunch of spikes launching at her. Unable to react quick enough, the spikes impale her entire body. Noticing Ophelia near the grotto, she staggers over to her and asks for help before spazzing out due to the snake venom from the spikes.

After Ophelia exterminates the snakes and sucks up their venom, Tammy graciously thanks her for the fast recovery, then eagerly returns to her tomb raiding, despite Ophelia's disapproval.

Similar to her brother, Tammy seems quite determined to obtain her desired goal, despite the mishaps she encounters along the way. Tammy is shown wearing casual explorer gear, along with a cute little bow she has tied onto her belt. Her hat covers her messy hair bun. Furthermore, underneath her shirt, she wore a pink bra with a leopard/cheetah/jaguar pattern.

Extract the stakes with the tongs and rid the poison leftover with either the syringe or the cut and vacuum tactic. To take care of the unwanted snake guest, shock it with the car battery when it pops out from its flesh hole then chainsaw its body to damage it. It will retreat to its hole then pop out again. Redo the same shock and chainsaw for two more rounds, then the snake will flop over dead. Extract the snake and close up the wound(in Amateur Surgeon: Re-Generations you'll have to take care of leftover poison with the pizza cutter and vacuum.)

When you advance on to her stomach, there will be more stakes to extract, more poison to get rid of, and more snakes to kill. Remember not to take too long handling everything, for you'll have to replace Tammy's poisoned stomach. The organ transplant is the final part of the surgery.

Since Tammy's surname is Gracefuls, it is known that she might be a relative of Tommy Gracefuls. This is true since she mentions a brother during their childhood on horse riding. Furthermore, Tammy, much like Tommy, is accident prone and relies on failed theft, with Tommy being a regular burglar while Tammy being a tomb raider.

Tammy was originally planned to be a storekeeper in Amateur Surgeon 3, but this was scrapped.

Tammy appears as the second patient in the Supernatural Surgeries Blood Cup, inflicted with a terrible case of cursed idols.

Tammy was found in the Through The Ages Blood Cup. Specifically in the Partner Special of Herbie Vore; the third patient in the said Blood Cup.
